AIRMONITORING 53


Proven and reliable solutions for BTEX monitoring around airports


Emission monitoring system with low


parts-per-billion detection of ethylene oxide (EO) Ethylene Oxide (EO) is used in the manufacture of a wide range of consumer chemicals. It is also used by hospitals and the medical equipment industry as a sterilising agent for heat sensitive instruments and equipment.


MAX Analytical Technologies has recently introduced the EMS-10™/eo, a fully automated, FTIR-based gas and emissions monitoring system capable of accurately analysing gas streams for EO down to low parts-per-billion levels with rapid, sequential measurements – Even in the presence of interfering compounds that cannot be differentiated using traditional technologies such as gas chromatography.


Chromatotec have a history of adapting their technology to fulfi l the needs of very specifi c applications. Their airTOXIC auto-GC analysers with PID or the airmoVOC BTX analysers with FID based detection have already been deployed in international airports such as Tel Aviv, Seoul and Montreal.


These analysers are suitable for measuring background levels and low concentrations (ppt levels) for ambient air applications. These cylinder free solutions include embedded gas generators and calibration controlled by GC in rack or wall mounted box. They are mCERTS certifi ed and fully compliant with EN 14662-3:2015.

measurements Atmospheric Particulate Matter (PM) or aerosol plays a key role in atmospheric pollution as particles cause visibility reduction, act as clouds condensation nuclei, affect global climate change and are responsible for adverse health effects. Carbonaceous Aerosol (CA), typically emitted by incomplete combustion of fossil fuels related to traffi c, industrial processes and domestic heating, is one of the main fractions of PM especially in urban environments and it is very important from the climate change point of view too, since Elemental Carbon (EC), which, depending on the technique adopted to reveal it, can also be called Black Carbon (BC), is the primary responsible of light absorption and of the direct radiative effect of aerosol on climate. Nevertheless, the measurement of CA composition, though prescribed by national and European regulations, is at the moment a “work in progress” and no methodology that is both of simple use and suffi ciently robust seems to be available. Creating state of the art the measurement of light absorbing aerosols is still a challenging fi eld of expertise, even though fi lter- based on-line techniques (e.g. the aethalometer; the particle soot absorption photometer; the multi angle absorption photometer, among others) are widespread, it is widely recognised that they are affected by measurement and sampling techniques which must be accurately managed by skilled personnel.

With this in mind, Dado Lab have created a methodology, using their Giano PMx sequential sampler, for measuring the concentration of black carbon that adopts many of the advantages of commercially available instruments, in particular the possibility of obtaining a “real time” measurement by means of non-destructive techniques, and that can at the same time overcome some of their limits by exploiting different physical principles and allowing its integration into a sequential sampler.

A solution to diffi cult atmospheric pollution


The EMS-10™/eo FTIR analyser features the proprietary MAX StarBoost™ technology which specifi cally enhances the systems performance for EO measurement over its calibration range of 0-50 ppm. The system also includes a variety of other proprietary technologies that ensure EO readings are very stable and remain unaffected by zero drift and bias that can occur in continuous monitoring situations. Integrated into the system is a heated sampling pump that allows the EMS-10™/eo to handle hot and wet samples, making it ideal for monitoring a wide range of stationary emission sources. MAX Analytical can provide complete factory EO monitoring solutions including ambient air monitoring, sample probes, heated lines and ATEX compliant enclosures.

from 5ppm to 5000ppm with minimal detection limits averaging from 0.05ppb to 0.5ppm. To ensure accordance with the sample conditions, the nCLD 800 Series is modularly designed, thus providing tailor- made solutions. For instance, a dual sample inlet, two parallel gas flow streams with heated sample lines, two reaction chambers with specialized metal converters, an internal pump and pressure regulation, are only a few possible adaptations. Furthermore, the nCLD 822 CMhr with its catalytic converter allows a specific assessment of the ammonia slip in SCR systems.
